大佬好。
我在调用iOS的方法时，方法内部使用了一些UIView，但是报错了，说是不在主线程。
所以想问一下，dart -> native，默认会在非主线程调用吗？怎么样可以让这个调用发生在主线程呢？

默认是同步调用到 Native，那么此时是在 flutter-ui 线程，并不是 iOS 的主线程。所以 DartNative 也支持切线程（GCD），比如这个例子：

dart_native/dart_native/example/lib/ios/unit_test.dart

Line 175 in dc99cfd

.performAsync(SEL('currentThread'), onQueue: DispatchQueue.global())
